X-ray imaging of flare loops and coronal arches [PDF]

open access: yes
HXIS (Hard X-ray Imaging Spectrometer) results related to preflare, flare-decay, and post-flare phases in the solar corona are summarized. Particularly discussed are miniflares, long-lived X-ray enhancements along filament channels, flare precursors ...

Three Types of Solar Coronal Rain during Magnetic Reconnection between Open and Closed Magnetic Structures

open access: yesThe Astrophysical Journal
Coronal rain (CR) is a crucial part of the mass cycle between the corona and chromosphere. It includes flare-driven CR and two types of quiescent CR, along nonflaring active region closed loops and along open structures, separately, labeled as type I ...

The Hydrodynamic Thermal Continuum, with Applications to Stratified Atmospheres and 1D Coronal Loop Models

open access: yesThe Astrophysical Journal
Using both analytical and numerical means, we demonstrate that linear stability analysis of a hydrodynamic stratified atmosphere or a 1D coronal loop model in nonadiabatic settings features a thermal continuum corresponding to highly localized ...

Investigating the Behavior and Spatiotemporal Variations of Green-line Emission in the Solar Corona

open access: yesThe Astrophysical Journal Supplement Series
Understanding coronal structure and dynamics can be facilitated by analyzing green-line emission, which enables the investigation of diverse coronal structures such as coronal loops, streamers, coronal holes, and various eruptions in the solar atmosphere.
